TABLE.

To all whom it may concern:

Be it known that I, FRANK C. RownLL, a citizen of the United States, residing at Ilion, in the county of Herkimer and State of New York, have inventedcertain new and useful Improvements in Tables, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to a table and I de-' clare the following tobe a full, clear, con-i cise and exact description thereof sufficient to enable any one skilled in the art to which it 'appertains to ,make and use the same reference being had to the accompanying drawings in which like referencecharacters j refer to like parts throughout the specification.

an inexpensive extension table adapted by simple mechanism to enable either end thereof when moved to move the other end simultaneously in a reverse direction, there by minimizing the labor of enlarging the table when it is found desirable to do so.

The invention further contemplates the use of rollers to serve the function of ball bearings whereby the customary difiiculty of pulling'the end members of a table apart,

because of their adhesive tendency, is

remedied. lhe table also may embody a central solid pillar or a dividable pillar for elevating the table at a suitable height.

These objects and others are acomplished by the devices described" and illustrated in the following drawings in which Figure 1 is a perspective viewof a table with'a dividable central pillar; Fig. 2 is a plan view looking from beneath upward and the raceway in section; Fig. 9 is a perspective view of a table having a non dividable central pillar for a support; Fig. 10 is a detail enlarged of a spring employed.

Referring more particularly to the drawings the table top proper before the addi- Specification of Letters Patent.

The object of the invention is to provide tion of extra leaves, ispreferably circular in formation and comprises end members land 2. To theunder surface o fmember I are secured rails 3 and 4 and to the undersurface of memberQ are secured rails 5 and.

{5. These rails are shownin the shape of an inverted U and are adapted to permit the sliding movement therealongof counter rails or raceways 7, 8, and11, 12secured. to sliding blocks 4 9 and 10 respectively. Counter rails; 7 8, l1 and 12 are provided with a base 14-v and right angularly disposed flanges 1515 at the top adapted to Iform Patented Nov. 3, 1914. Application filed November 26, 1910. Serial No. 594,337. v

upper bearings for rollers 16,.as bases 14: are 1 adapted to formlower bearings or raceways for rollers 16,having axles 17 with bearings in rails 3, 4, 5 and 6. Rollers 16 are preferably disposed adjacent the inner ends and center of said rails 3, 4, 5 and 6, although they may be disposed at nearer intervals if it is found desirable to have them so arranged. r

.The invention also contemplates astill further extension of the table or a table with a dividable central pillar. Referring to Figs 1 and 1, more particularly, I there show the table thus constructed. In this construction blocks 9 and 10 are. divided into three parts each 31,32 and 33, said parts being slidingly engaged by means of dove.- tailed oints as seen in Fig.4. Counter rails 8, 12 and '7, 11 are mounted respectively upon blocks .31 and .33. In this instance 'whenqend members 1 and 2 are extended a given distance, rollers 16,-mounted centrally of rails 3, 4,5, and 6 abut against stops 31 secured to the outer ends of counter rails 7;,

so that if either end member 1 or 2 is moved farther outward, blocks31 and 33 will be forced to slide longitudinally along blocks '8, 11 and 12 in the paths of said rollers 16,

blocks 3131 and is blocked up by blocks 1 38 whereby said cross beam 35 will not con tact with blocks 32 or 33. Likewise cross beam 36 is secured to blocks 32 -32 and is blocked up by 3939, and so with cross beam 37 blocked'up by 40. To cross beam 35 is secured a half 1-1 of the dividable pillar and to cross beam 37 is secured the other half 42 of the dividable pillar, and to cross have secured adjacent the bottom thereof a dividable disk having parts 44: and 45. Said parts 4A and 45 each carry two legs as 46 and 47 having casters 48. The center pillar 43 has the function of a fifth leg and thus tends to give stability. However, it may be found desirable to dispose legs at diflerent locations along cross beams 35, 36 and 37.

In order to hold blocks 31, 82 and 33 from moving a longitudinally with reference to each otl1er,when it is found desirable to eX- tend the table only to the distance permitted by the sliding of rails 3, 4, 5 and 6, along counter rails 7, 8, 11 and 12, I employ a spring latch 49, secured at one end to one of the cross beams as 37 and having a lug 50 adapted to engage the remote edge of cross beam 85 and thus hold said cross beams in the position shown in Fig. 21 End 51 of latch 4E9 is provided with a handle 52 adapted to be a ready means whereby to disengage lug 50 from the edge of cross beam35.

It will be seen that the diameter of rollers 16 is nearly equal to the distance from base it to flange 15 of the counter rails, whereby the end members 1 and 2 and parts connected therewith may be held rigidly when in extended position.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. In an extension table, the combination with a dividable top and dividable means supporting the top, of cross-beams supported on each part of said dividable means, a latch carried by said beams and adapted to hold them together, blocks mounted one on each of said beams, counter-rails mounted on certain of said blocks and top-rails set into the counter-rails having flanges at the top and parallel with the bottom and the toprails having wheels riding in the counterrails between the flanges and the bottom and stops fixing a limit to the movement of the (or by releasing the latch may be separated beyond said limit).

2. In an extension table, the combination with a dividable'top and dividable means supporting the top, of cross-beams supported on each part of said dividable means, blocks mounted one on each of said beams, counter-rails mounted on certain of said blocks and top-rails set into the counterrails and supporting the portions of the top, the said counter-rails having flanges at the top and parallel with. the bottom and the top-rails having wheels riding in the counter-rails between the flanges and the bottom and stops fixing a limit to the movement of the top-rails relative to the counter-rails, by which combination the parts of the top may be separated only to the said limit by reason of the connected condition of the said beams.

3. In an extension table, the combination with a dividable top and dividable means supporting the top, of cross-beams supported on each part of said dividable means, a latch carried by said beams and adapted to hold them together, blocks mounted one on each of said beams, counter-rails mounted on certain of said blocks and top-rails set into the counter-rails and supporting the portions of the top, the said counter-rails having flanges at the top and parallel with the bottom and the top-rails having wheels riding in the counter-rails between the flanges and the bottom and stops fixing a limit to the movement of the top-rails relative to the counter-rails, by which combination the parts of the top may be separated only to the said limit by reason of the connected condition of the said means or by releasing the latch may be separated beyond said limit.

In testimony whereof I have hereunto aifixed my signature in the presence of two witnesses.
